I've been seeing this question a lot lately in the Model Editing help section, so I decided to make a guide on it. This is a guide for fixing your character size and move speed on race swaps. This may also be of assistance for any swap that you want to resize.
Tools needed:
My Warcraft Studio - MyWarCraftStudio-VistaFix.rar (MAY work for Windows XP users)
Glitchy's Model Editing Suite - http://www.mmowned.com/forums/model-editing-guides-programs/79372-glitchy-s-mes.html
Lets assume you have a race swap from Glitchy's MES or one that you downloaded from MMOWNED. In this case we have a Tauren Male -> Blood Elf Female. However, when you load the patch in game you realize that the Blood Elf Female is far too big. Don't worry, this guide should assist you in fixing the problem.
1) Open up My Warcraft Studio, load your race to race patch that you made or downloaded, select the .m2 (left click it), and then extract the .m2 file to your desktop (do this by right-clicking and hitting extract), in this case tauren.m2. While doing this, right click again on the .m2 and click copy treepath. Paste the treepath into a notepad.
Note: The .m2 file will be under Character -> Your Race -> Your Gender in My Warcraft Studio.
2) We are now going to use Glitchy's Model Resizer Tool. You can find this tool by clicking on the advanced apps box (last box), then holding your mouse over m2 tools, then clicking model resizer. Click Load and Navigate to the .m2 that you just extracted. In the model modifier box and type how many times you want to shrink or enlarge the model by. In this case we are going to be shrinking by about 1.35x. Finally click the shrink or enlarge button. In this case we will be shrinking the model.
*The model is now shurnk, Glitchy's MES will let you know with the message box.
3) We are now going to fix the run speed of the animation so that it looks better in game. Again we will be using a tool made by Glitchy. Go to advanced apps -> Animation Tools -> Animation Editor. Load the same .m2 file that you have been configuring. Under the updated Values blue text you will see a drop down box where you can select animation. Select the run animation. Over to the right you will see a bunch of values. Go down to the Value that says moving speed to the left. Select that value. Change it from 6.94445 -> 5.24445 (This works for Tauren Male -> Blood Elf Female, and should work if you are scaling the model about the same amount, you may have to play with this number a bit until you find the prefect speed. Also note that if you are increasing the model size just add about 1.7 instead of subtracting 1.7 from the moving speed). After you have changed the moving speed value, click save settings. Again you will be notified that Glitchy's MES has done the task by a pop up window that says "Your done you may now eat cake!".
4) We are finally almost done! Your .m2 is now modified with the correct size and movement speed. Close Glitchy's MES and go back to My Warcraft Studio. Go to Pack -> Edit Archive and select your original race swap patch. Right Click on the .m2 and click remove file. It will as Are you Sure: Click Yes.
5) Now click pack -> add file to archive. Click the "..." and navigate to your modified .m2 file. Go to your notepad file and copy the treepath that you found earlier. Paste the treepath over the file name and click ok.
6) You have no completed the task. Click the save button in My Warcraft Studio and close it. Put the patch in your data folder. Make sure that you have the MEF in your wow root directory. Start wow through the MEF and admire your work.
Happy Editing!
Note: If you are having trouble with resizing try this advice. I haven't tested it myself, but it seems to work for some people. I'll try to figure out more about it when I have the time. I didn't need this, but some of you may.
If you are unsure how to resize weapons manually here is a guide: RapidShare: Easy Filehosting (Credits go to SchnuBby). It's the same concept as increasing the size of your character model. Just find your weapons/armor and increase it by the same amount that you increased your character model by. Part of the video is not in English. Hopefully you can figure it out. I think the main part that isn't in English are the copy and pastes.
Note: The .m2 file path that you find in Glitchy's MES can be in any of the various Blizzard patches. It is not necessarily in Patch.MPQ.
